Total Mobile Audio is/was affiliated with JL Audio. I hear it's decent equipment, but I've never used any TMA gear.
The Profile amps do a fine job, especially given their cheap pricetags. I've had 3 of them for years now. They've been in dozens of vehicles and still work as good as they did on day 1. I don't think you could find a better amp for the price. You could buy 3 or 4 of them with your budget. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
